RUNNING REGISTER Application April 22, 1936, Serial No. 75,705

15 Claims.

This invention relates to registering mechanisms and more particularly relates to novel methods of and apparatus for angular and axial adjusting means for rotating members.

Machines which operate upon advancing sheet material, for example corrugated board, box blanks and the like, generally comprise a plurality of revolving members which perform successive operations upon the sheet. These ma- 10 chines are adjustable for different sizes of the product and the drums are approximately set into registering position while the machine is at rest. Accurate registration of the drums, particularly of the multi-color printing and the 15 slotting drums, is not feasible except after test runs upon the material are made.

To expedite the accurate angular and axial alignment of the successive drums, prior registering devices have been developed to perform the adjustments while the machine was in operation in order to avoid starting up and stopping. An important advantage of running registering devices is that rapid compensation for speed changes and slippage of any particular drum or 25 of expansion or contraction of the product due to elasticity or other changes therein may be readily effected while the machine is maintained in operation.

The prior running registering devicesincluded 30 clutches and manual hand adjusting operations which were necessarily slow and inconvenient. I contemplate a running register mechanism which dispenses entirely with clutch engagement or disengagement of the rotating drum and maintains a positive driving connection between the rotating drum and its motive power. The Vernier adjustments of my present invention are performed semi-automatically. The motive power for the drum is employed for effecting the Vernier axial and angular drum adjustments.

This invention is in the nature of an improvement of my co-pending application Serial No. 56,956, filed December 31, 1935, where the fundamental principles of the Vernier angular and ,5 axial adjusting means are disclosed. The Vernier registration of the drums is preferably performed while the machine is running slowly so that the operator may readily determine the correct drum positions with a minimum of stock wastage.

50 However, if the initial registration should require re-adjustment, for example due to the higher normal speed of operation or due to slippage or the like, each drum is adjustable during any speed of its operation.

The elimination of clutch connections between the motive power and the rotatable drum is accomplished in-my present invention by surrounding the registering mechanism with a sleeve which is connected to the internal mechanism which connects to the drum shaft by a worm 5 gear arrangement to complete the positive driving connection from the drum shaft and the motive power. Angular displacement of the drum shaft with respect to the external sleeve is eifected by rotation of the worm in a manner to be described in detail.

Slotter heads are generally adjusted axially before the machine is started up and circumferential adjustment alone is usually necessary during operation. My present invention is applicable to angular registration without the axial adjustments and accordingly I disclose hereinafter a preferred embodiment of such an application.

It is accordingly an object of my present invention to provide novel methods of and apparatus for running registration of rotating drums.

Another object of this invention is to provide a novel running register which maintains a positive driving connection between the motive power and the rotatable drum.

A further object of this invention is to pro-- vide a novel semi-automatic running register for optional angular or axial drum adjustment.

Still a further object of this invention is to providea novel semi-automatic running register for angular adjustment.

Other objects of my invention will be evident in the following description taken in connection with the drawings, in which:

Figure 11 is the corresponding modification of the register drive for the embodiment of Figure 10.

In applying my present invention to printer drums and the like, where both angular and axial adjustments are required, the preferred modification illustrated in connection with Figures 1 to 9 is disclosed to particularly set forth the invention. Referring to Figure 1, ll] represents the printer drum or rotating member which requires the axial and angular adjustment for accurate registration upon a moving sheet or stock between the drum l9 and presser roller Drum I8 is normally rotated by motive power impressed upon gear l2 which is secured to shaft l3. Shaft I3 is supported on frame members l4 and I5 housing roller bearings Hi and I1 respectively (Figure 2). Gear |2 engages gear |8 which is bolted to sleeve 29. The shaft 2|, of drum IE3 is normally rotated by the motivation of gear l8 and sleeve 26 as will be described in detail hereinafter. The mechanism housed within sleeve provides the registry adjustments in accordance with the present invention which adjustments normally rotate as a unit with sleeve 20.

A further sleeve 22 is secured to sleeve member 23 within sleeve 2 by screws 24, and is rotated therewith. Spur gear 25 is integral with sleeve 22 and engages with gear 28 to normally continuously rotate a friction cone 21. Friction cone 21 supplies the power for motivating the axial and angular drum adjustments under the control of hand wheel 28 as will be described hereinafter. Extension bracket 39 from frame member 3| supports the friction drive mechanism co-acting with friction cone 2'! and bracket 32. A guard 33 is attached to the outside end of bracket 32 for housing the changeover mechanism which the operator controls by hand lever 14 to effect either the axial or angular drum alignment.

In accordance with this invention, the full angular or 360 control of drum I0 is divided into two operations. The first operation resolves itself into a manual adjustment of the drum ID to the approximate registry position while drum I0 is at rest. It is a simple matter for the operator to approximate the drum registry for example within ten degrees of the drum angle. The second operation is the semi-automatic Vernier adjustment of the drum while rotating for precise angular registration.

The axial adjustment of drum H! is independently accomplished while the drum is in rotation. It is preferable to perform the longitudinal and the final axial adjustments While the machine is operating at a relatively slow speed in order to prevent undue wastage of stock until accurate adjustment is achieved and in order to more readily effect the adjustments. However, realignment of the drum while the machine is in operation is preferable at the normal operating speed.

The approximate angular adjustment of drum I9 is accomplished by operation upon the square head 35 with a hand wrench while drum H1 is at rest. respondingly rotates the worm 36 (Figure 3) which engages with worm gear 31 set into sleeve 23. As more clearly represented in cross-sectional view Figure 2, shaft 2| of drum ||I is rot-atably linked with sleeve 23 'in the following manner:

The rotation of the square head 35 cor- Extension 2|a of shaft 2| contains a key 40 engageable with the extended keyway 4| in sleeve 42. Sleeve 42 supports the spur gear or pinion 43 on the threaded shaft or screw member 44.

Figure 9 is a perspective illustration of the end portion of sleeve 42 supporting gear 43 on threaded shaft 44 in bosses 4546. Sleeve 23 surrounds sleeve 42 and contains the worm gear teeth 31. At the end portion of sleeve 23 cor responding to the position of spur gear 43 is contained members 41 containing stop plates 48 for abutting the corresponding ends 4950 of shaft 44.

By rotating worm 36 at its square head 35 the intermediate sleeve 23 is revolved angularly with respect to the outer sleeve 20. Members 48 mounted in sleeve 23 abut ends 50 of shaft 44 rotating sleeve 42 therewith. Sleeve 42 is carried along with the rotation of sleeve 23 so that the same angular displacement between intermediate sleeves 23 and outer sleeves 29 is accomplished. Since sleeve 42 contains keyway 4|, shaft 2| will be correspondingly angularly displaced with respect to housing sleeve 29 as will now be understood.

Angular adjustment of drum I3 is accordingly feasible over 360 of rotation, adjustable in a clockwise or counterclockwise sense in accordance with the rotation of worm 36. It is to be understood that the manual adjustment of drum ID by means of a hand wrench rotation of worm 36 is performed while driving gear [2 is at rest. Drum I0 is approximately adjusted into angular registration in this manner, and a positive drive connection is maintained between the drive gear I2 and drum l0.

Precise angular registration is accomplished semi-automatically. The principle of the Vernier adjusting mechanism of the present invention is disclosed in my co-pending application Ser. No. 56,956 referred to above. As Will be hereinafter described in detail, an axial motion is imparted to rack member 5| in proportion to the required final angular adjustment. The transverse motion of member 5| is accomplished while drum I0 is running by the motive connection of driving gear [2 and gear [8. The rotation of gear |8 carries therewith housing sleeve 28 which contains the worm 36 in turn meshing with worm gear 31 so that sleeve 23 is normally rotated therewith, in turn rotating shaft 2| in the manner already described. Transverse movements of rack member 5| will perform corresponding small angular displacements of sleeve 42 with respect to sleeve 23 to correspondingly angularly displace revolving drum l0 forwardly or rearwardly with respect to the driving gear members l2 and I8.

As described in my co-pending application already referred to, the relative angular displacement due to the transverse motion of rack member 5| is accomplished in the following manner: Rack member 5| encloses shaft 52 which is connected to extension shaft am by pin 53. Figure 9 is a perspective illustration of the gear member 43 and rack member 5| in sleeve 42. Rack teeth 54 of rack member 5| engage gear 43 so that an axial movement of rack member 5| will correspondingly rotate the gear 43 clockwise or counter-clockwise. The upper half of Figure 3 is a cross-sectional illustration through the angular displacing mechanism comprising gear 43. Gear 43 is internally threaded with teeth 55 to mesh threads 55 of screw member 44. Since gear 43 is restrained from axial movement by bosses 45-46, the screw member 44 will be forced to "rnove axially in accordance with the rotationof gear 43; Rotation of screw member 44 is prevented by key 38 fixed in bosses 4546 and keyway 39 in the member 44.

Ends 49 and 5c of screw member 44 are rounded to permit a sliding movement with respect to plates 48. If the rotation of gear 43 (actuated by rack member 5!) moves screw member 44 towards the left, the end 49 will abut plate 48 and force its supporting mechanism to the position illustrated in Figure 4. Figure 4 shows about a ten degree angular shift of screw member 44.

Sleeve (32, which supports screw member 44 and gear 43 is correspondingly angularly displaced with respect to sleeve 23 (which contains plates 48). Shaft 2i will accordingly be angularly displaced since it is keyed thereto by keys 4Q. It is to be understood that this angular displacement of drum H! with respect to gears l2 and i8 is accomplished in its running condition. A ten degree adjustment in either direction from neutral may readily be made using this reaction principle. Precise split-hair angular. registry of drum it is performed by operation of rack member 5|.

Power for the axial movement of rack member 5! is transmitted from revolving friction cone 2'! as follows: As already described, friction cone 2'! is normally rotated by gear 26 meshing with gear 25 (Figures 1 and 2) A stud 5'! mounted in extension 58 of bracket so rotatably supports friction cone 21. Co-actable friction disks 60 and 5! are independently. engaged with gear 2? to rotate their common shaft 52 to which they are pinned in either direction (Figures 6 and 7).

Shaft 32 is supported in yoke 63 extending from bracket 38 attached to the frame. An externally threaded sleeve 2o co-acts with the internally threaded sleeve 53 set in one end of yoke 63. Shaft 52 is rotatable within sleeve 29. Hand wheel 28 is connected to sleeve 29 by set screw 28. The set screw 223 projects into an annular groove $2 on shaft 62 so that shaft 62 is free to rotate with respect to hand wheel 28 and sleeve 29 but is constrained to move axially therewith. Roller thrust bearings ill-Hi are attached to either end of sleeve 29. A nut 54 is pinned to shaft 52. Worm is slidably keyed to the opposite end of shaft 52 by key 66. Roller thrust bearings H3EU are attached to the opposite ends of worm B5.

Optional engagement of friction disks 5!! and 6! with friction gear 21 is effected by suitable rotation of hand Wheel 28 as will now be evident. Rotation of hand Wheel 28 will correspondingly move sleeve 29 outwardly or inwardly to engage disks 60 or 8! respectively. Clockwise or counterclockwise rotation of shaft 62 will correspondingly rotate Worm 61 which is connected to shaft 68 by pin 69. This arrangement of the driving attachment of the shaft 68 to the friction gear 21 is accomplished by the operation of hand wheel 28. Hand Wheel 28 is not rotated since shaft 62 is free to rotate within the sleeve 29.

Shaft 68 is accordingly motivated from cone 2? in either sense according to the optional engagement by hand wheel 28. Spur gear H is slidably keyed to shaft 68 and rotates therewith. Spur gear ii is alternatively engageable with gear 12 or gear 13 according to the position of the threeposition lever 14. As will be described hereinafter, gear i2 corresponds to the angular registration of drum iii and gear 13 corresponds to the axial registration of drum it. The engagement threaded to engage threaded member 84.

move axially with respect to gear 13.

of spur gear H with gear 12 or T3 is accomplished as follows:

Referring to Figures 5 and 8, lever, i4 is attached to rod 15, the opposite end of which is connected to yoke 16. A pin 'I'I projects from lever 14 from a contained spring 18 to rest in corresponding detents in bracket arm 853. Three detents corresponding to neutral angular and axial engagement of gear 1| for effecting corresponding drum l0 registration are set in the bracket arm 80. Arms 8|-8l of yoke 16 engage hub 82 of gear "H as illustrated in Figure 7. Engagement of gear I l with either gear 12 or gear 13 is accomplished by merely shifting lever M to the proper position, preferably when friction cone 2? is not engaged. For angular adjustment of drum I 0, gears H and 12 are engaged.

Referring to Figure 2, the hub 83 of gear 12 is Gear 12 is constrained from axial movement by projection 85 of housing 33 in its hub 83. Threaded member84 is slidably keyed to sleeve 85 by key 81. Rotation of gear 72 accordingly forces threaded member 84 into axial movement. End portion 88 of threaded member 84 is connected thereto by semi-circular extension 89. Extension 89 is slidably keyed to bracket 32 by key 98 as illustrated in Figures 2 and 6, to restrain threaded member 84 from angular movement.

Axial displacement of member 84 due to rotation of gear 12 accordingly carries end portion 88 axially. Inner racer of ball bearing 9! is attached to member 88. Ball bearing 9| is set into extension hub 92 of rack member 5! (Figure 2). It is to be understood that member 83 is free to move axially with respect to shaft 52 and bracket 32; and rack member 5|, with respect to shaft 52.

Transverse movement of rack member 5| is accordingly effected by rotation of gear 12 as will now be understood. When lever 74 is moved. to engage gear "H with gear 72, drum H1 is ready for precise angular registration. Moving hand Wheel 28 outwardly or inwardly will cause corresponding disks 60 or 6! to engage with revolving friction cone 2?, to correspondingly move rack member 5! axially. Gear 43 is accordingly rotated to perform the angular adjustment of drum H3 in a manner hereinabove described in a clockwise or counterclockwise sense.

Axial registration of drum I0 is accomplished by engaging gear H with gear 13 by simply moving lever 14 while friction gear 21 is disengaged. Hub 93 of gear H is internally threaded to engage with the finely threaded sleeve 85. pitch of threads 94 of sleeve 86 is small to permit Vernier axial adjustment of drum ID. Flange 95 is bolted to gear 13 and is set into hub 83 of gear 12 to prevent axial movement of gear l3. When gear 13 rotates, sleeve 85 must accordingly A ball bearing 96 connects the end of sleeve 94 with an extension 91 of shaft 52. Shaft 52 is accordingly free to rotate with respect to sleeve 86 which carries shaft 52 axially along with it. Axial movement of sleeve 86 resulting from the rota tion of gear 13 accordingly moves shaft 52 therewith to correspondingly move the shaft 2! of drum If), the end 2| a of which is pinned to shaft 52. It is to be understood that the axial adjustment of drum I 0 may be made in either direction according to the engagement of cone 2? with either disk 60 or BI; and that this adjustment is effected when the drum is in rotation.

Theaccurate angular and axial adjustment of The drum l may be locked byturning the thumb- 1 screws 98 and 99 respectively (Fig.1). Thumbscrews 98 and 99 operate corresponding plates H30. As illustrated in Figure 5, plate I00 abuts 5 the surface of gear 12 when the rod I!!! to which it is riveted, is moved downwards by thumb-screw 98 turning on the threaded portion I02. Plate 160 is guided by pins I03. Other well known adjustment locking means may be used. to maintain the vernier adjustments of drum Hi.

When re-alignment of drum I9 is necessary due to speed change or slippage, or due to the stock itself, the plates I00 are released from gears 12 and/or 73 to permit operation of the vernier angular and/ or axial registering mechanism.

The running register is also applicable to a revolving drum requiring only angular adjustment. For example, a slotter head is adjusted axially on its shaft while the machine is at rest and it is only necessary to perform angular registration while the machine is in operation. In Figures and 11, I illustrate a modification of my present invention as applied to a slotter head requiring only angular registration adjustments.

Figure 10 is a partial cross-sectional illustration corresponding to the Figure 2 of the first described embodiment. Since axial adjustments are not required, the rod 52 extending from the shaft Zia through the vernier adjusting mechanisms is not required. 2|a corresponds to the shaft 21a. of Figure 2 and is slidably keyed to sleeve 42a by key 49a in keyway 41a. Sleeve 42a supports the screw member 44a and the gear 43a in a manner hereinabove described in connection with the similarly numeralled members without the added letter a of the former angular and axial embodiment. Rack member 54a coacts with gear 63a to effect the vernier angular registration of the drum (not shown) attached to the shaft 21a.

For simplification in the presentation of the modification in comiection with Figures 10 and 11, I have labelled the members of these views which correspond to members in the modification described in connection with Figures 1 to 9 with the same numerals and an additional letter a. The approximate angular adjustment performed while the drum is at rest, circumferentially adjustable over 360 is effected by an operation of the worm 36a supported in a housing sleeve a. which coacts with the worm gear 31a. of sleeve 3a in a manner already described.

The vernier angular adjustment is accomplished by transversely motivating rack member 5411. semi-automatically. Friction cone 21a; is supported on bracket 53a of extension bracket 30a. Spur gear a is attached to friction cone 21a and is driven by the co-acting gear 25a integral with sleeve member 22a bolted to sleeve 23a. Gear 25a is rotated through the rotation of the drum and corresponding sleeve members, as is understood.

Friction cone 27a is optionally engageable with either friction disk 60a or Gla (Figure 11) by operation of hand wheel 28a in a manner already described in connection with Figures 6 and '7 to eifect a clockwise or counterclockwise rotation of their common shaft 62a. The rotation of shaft 62a correspondingly revolves shaft 68a which is keyed to the gear Ha. Gear Ha engages with the gear 12a to effect the axial movement of rack member 54% in a manner to be described in detail. n

The structural difference between the modification of Figures 10 and 11 and the other embodiment resides in a permanent engagement of gears Ha and 12a and the elimination of the changeover lever 14 as will now be evident. The semi-automatic operation of the vernier registration is effected in a clockwise or counterclockwise sense by suitable operation of hand wheel 28a.

Referring now to Figure 10, the hub 83a of gear [211 is internally threaded and engages with the externally threaded shaft 84a. Shaft 84a corresponds to the threaded member 84 shown in Figure 2 and is not hollow since no axial adjusting shaft for the drum is required. In a similar manner, rack member 54a is also not hollow. The end portion 88a, of threaded shaft 840. is attached to the extension 92a of rack member 54a by a roller bearing Ma. The inner racer of roller bearing 9 la. is secured to the shaft extension 88a by nut I05. The outer racer of bearing 9Ia, is secured to extension 92a by nut I06.

Threaded shaft 84a is slidably keyed to bearing 32a by key 90a. Shaft 84a is accordingly constrained to move only axially and roller bearing 9 la permits the normal rotation of rack member 54a, within sleeve 22a. The transverse or axial motivation of rack member 84 is effected by suitable rotation of gear (211 through the coacting gear 1 la as driven from the friction cone 21a. The hub 83a of gear 12a has an annular groove retaining the collar 85;; and is accordingly restrained to rotate and is not movable axially. Rotation of gear 21a accordingly forces screw member 84a to the right or left according to the sense of its rotation. Axial movement of shaft 84a correspondingly moves rack member 54 to rotate the gear 43a which in turn effects the vernier angular adjustment of the drum member in a manner described in detail in connection with Figures 3, 4 and 9.

It is to be understood that my present invention may be applied to each of the several successive drums operating upon a sheet advancing through the machine to provide an independent registering mechanism for the respective drums. Printer drums are preferably provided with the angular and axial adjusting register described in connection with Figures 1 to 9 whereas slotter drums need only be provided with the angular register described in connection with Figures 10 and 11. The preliminary approximate angular adjustment of each drum is made while the machine is at rest. The slotter heads are then adjusted axially. The vernier angular and/or axial adjustments of the respective drums are made while the machine is running, preferably at a slow rate so that the operator may readily perform the necessary adjustments with a. minimum stock wastage. The vernier adjustments are then looked into position. Should re-adjustment of any particular drum be necessary in the normal operation of the machine such adjustment may be effected at the normal speed, if desired.

Although I have illustrated particular embodiments of my present invention, it will be evident to those skilled in the art that modifications may be made which fall within the broader spirit and scope thereof and accordingly I do not intend to be limited except as set forth in the following claims.
